Front Bezel
The bezel at the top front of the director includes an amber system error light-emitting
diode (LED) and a green power LED. The power LED illuminates when the director is
powered on and operational. If the LED extinguishes, a facility power source,
alternating current (AC) power cord, or director power distribution failure is indicated.
The system error LED illuminates when the director detects an event requiring
immediate operator attention, such as a FRU failure. The LED remains illuminated as
long as an event is active. The LED extinguishes when the Clear System Error Light
function is selected from the Product Manager application. The LED blinks if unit
beaconing is enabled. An illuminated system error LED (indicating a failure) takes
precedence over unit beaconing.
